ABSTRACT:
An electric golf cart that repeatedly travels around a given course of golf links is powered by a driving motor supplied with electric power from a driving battery. The electric golf cart is provided with a travel distance integrating unit, a memory, a battery charge and discharge integrating unit, and a discharge-per-course calculating unit. Mapping data is stored in the memory, which mapping data defines the relationship between the distance that the electric golf cart travels and the number of rounds that the electric golf cart has traveled. The number of rounds that the electric golf cart has traveled is calculated by the discharge-per-course calculating unit based on the travel distance obtained by the travel distance integrating unit along with the mapping data. Then, the number of rounds obtained and the discharge calculated by the battery charge and discharge integrating unit are utilized to identify the discharge of the driving battery per course.
